JOHN J. PATTON, OF NEW YORK, N. Y.

TIRE.

To all who'ra it may concern:

Be it knownthat I JOHN J. PA'r'roN, a-

citizen of the United tates, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Tires, of

specification.

The object of my invention is'to afford a tire havingexcep ional tractional and antiskid qualities .adapted' particularly to the conditions and requirements of heavy'trac-' tion as in the case of auto-motors and vehicles designed for commercialtransportation; The invention consists in the s ecific construction, arrangement and com ination of I icorrelated parts herein after described and I section taken upon plane 0 claimed specifically.

In the'accompanying drawings, Figure 1, is a face view of aporti-on of my improved tire spread horizontally for .convenience o illustration, and broken away in various places the better to show the structure;'Fig. 2, is 'a sectional elevation of a portionv of the tire, the sectional part being taken upon the plane of the line 22- Fi 1;' Fig. 3, is a Fig. .1 Fig. 4, is plane of the line longitudinal section of a portion '0 ripheral basetire plate Fi 6, is an elevation of the tire plate on a re uced scale.

A represents any ordinary rim ofa wheel, on the periphery of which is shrunk the tire base plate B, formed with the transverse channels '1), in which are secured rubber or other elastic. resilient material D, held in place by transverse cap flanges E, and circumferential side flange plates F.

which constitute channel I). These set screws do not protrude. Into the wooden rim; and their heads are The side walls I), b, of the channels'b, are made integral with the tire base plate B, and form supports for which are-secured in positionby set screws e,

engaging with female screw threads formed for their reception directly within the flan es the sidewall b,-b, of t e countersunk in the cap' flange plates E,.by preference, as shown .in- F1g '4, although this is not absolutely essentia The transverse channels b, preferably. extend obliquely across the base form seats for made of rubber or other suitable elastic Specification of Letters Patent.

is very simple and eflective,the'

arduous requirements of heavy traction.

Furthermore, the operation of assembling and securin the parts is simplified and facilitated, w ile'provision is made for the substitution of treads when desirable without the removal of other parts. That is to say 'a tread may be removed from above or radially and another substituted by simpl slightly loosening. one circumferential si e particular tread channel '1), involved, thus allowing a tread to tion an another-sprung into position with out detaching either the side plate or the cap flange plates.

them therein by the cap flange screwed directly onto the channel sidewalls or artitions b, b, I obviate the use of indivi ual channel pans, cores, etc., embedded or secured directly in or to each rubber tread; such devices not only being ob'e'ctionable b reason of cost of construction ut also ten structure andshorten the because in practice such devices increase friction, heat the rubber, and increase the wear and tear of parts.

- Another important feature of my improved tire structure is'thatthe, fla

and supplementing the screw bolts e, e, In attaining-a rigidstructure, as-clearl shown in Fig. .4. In this; connection it is to be" noted that the bolts (1', which secure the circumferential side flange plates F in position,- extend at ht angles to the screw bolts e, e, by which 0 caps are screwed to the side walls or partitions b,-an arrangement most effective in meeting'and counteracting the radial strain"arising-from the alternate. compression and expansion of the rubber treads I plates comprising -metallic base plate shrunk onto therim of side and end shoulders,

What claim as-my invention and desire to secure by Letters Patents is, v A wheel tire ofthe character designated, a continuous one piece annular the wheel, formed with eripheral diagonal ribs which are rectangu ar in cross section,

elastic resilient tread sections seated directly the said diagonal in the channels between ribs, said tread sections being formed with cap .fiange plates mounted upon, secured to, and overlapping said diagonal ribs and engaging the side shoulders of the said tread sections on either side, circumferential and bolts securing the JOHN J.
